Textbook Question
Chapter 9, Problem 1CSD
At the beginning of this chapter, we discussed research by J. Sholl et al. on the relationship between gender and sense of direction. Recall that, in their study, the spatial orientation skills of 30 male and 30 female students were challenged in a wooded park near the Boston College campus in Newton. Massachusetts. The participants were asked to rate their own sense of direction as either good or poor.
In the park, students were instructed to point to predesignated landmarks and also to the direction of south. For the female students who had rated their sense of direction to be good, the table on page 368 provides the pointing errors (in degrees) when they attempted to point south.
- a. If. on average, women who consider themselves to have a good sense of direction do no better than they would by just randomly guessing at the direction of south, what would their mean pointing error be?
- b. At the 1% significance level, do the data provide sufficient evidence to conclude that women who consider themselves to have a good sense of direction really do better, on average, than they would by just randomly guessing at the direction of south? Use a one-mean t-test.
- c. Obtain a normal probability plot, boxplot, and stem-and-leaf diagram of the data. Based on these plots, is use of the t-test reasonable? Explain your answer.
- d. Use the technology of your choice to perform the data analyses in parts (b) and (c).
- e. Solve part (b) by using the Wilcoxon signed-rank test.
- f. Based on the plots you obtained in part (c), is use of the Wilcoxon signed-rank test reasonable? Explain your answer.
- g. Use the technology of your choice to perform the required Wilcoxon signed-rank test of part (e).

Gender and Direction. In the paper “The Relation of Sex and Sense of Direction to Spatial Orientation in an Unfamiliar Environment” (Journal of Environmental Psychology, Vol. 20, pp. 17–28), J. Sholl et al. published the results of examining the sense of direction of 30 male and 30 female students. After being taken to an unfamiliar wooded park, the students were given some spatial orientation tests, including pointing to south, which tested their absolute frame of reference. The students pointed by moving a pointer attached to a 360◦ protractor. The absolute pointing errors, in degrees, are provided on the WeissStats site.
a. Use the Mann–Whitney test to decide whether, on average, males have a better sense of direction and, in particular, a better frame of reference than females. Perform the test with α = 0.01.
b. Obtain boxplots and normal probability plots for both samples.
c. You used the pooled t-test to conduct the hypothesis test. Based on your graphs in part (b), which test is…

- Mental rotation times will be measured in a fashion similar to that described by Shepard and Meltzer (1971). After a block of practice trials, each student will receive 12 trials with a non- rotated comparison stimulus (0 or no rotation). Then, students will be tested for 12 trials with a comparison rotated at a 60 degree angle, followed by 12 trials with a comparison rotated at a 120 degree angle. Finally, they will receive 12 trials with a comparison rotated at a 180 degree angle. The angles will always be tested in this same order. A) What is the independent variable in this experiment?

- An important issue in court cases is the accuracy of eyewitness testimony. Behavioral scientists have suggested eyewitnesses can be influenced by how a question is phrased. A researcher conducts a study where 15 people watch a film of an accident in which Car A runs a stop sign and hits Car B at a speed of 20 miles per hour. After watching the film, she asks each of the 15 people to estimate Car A's speed at the moment of impact (they do not know the actual speed). However, the question is phrased three different ways. Five people are asked, “How fast was Car A going at the time of the accident with Car B?” Another five are asked, “How fast was Car A going when it hit Car B?” The last five are asked, “How fast was Car A going when it smashed into Car B?” An investigator wants to determine if estimates of speed vary as a function of the wording of the question, with more extreme wordings leading to higher estimates, at 0.05 level.
